MTN NEW APP- DISASTER

I have logged a query the beginning of May regarding the New MTN App that is unable to verify my identity. After phoning and sending emails on numerous occasions with the Screenshot of the error message as well as a certified copy of my ID and nothing is happening.

The emails was send to: *** BackOfficeSupport *** ***

I was also advised to check my balances and buy data etc through the usd code, but that doesnt even work properly, whenever I try to buy for instance 2.5gb data it only gives me 500mb data.

Some assistance will really be appreciated!!!!!!
